Migration process

April 2, 2020

Online database transformation

Schemas can be migrated from Oracle databases to destination databases. During the migration process, schemas can be revised to simplify the procedure to construct destination databases.

Database profiling

Compatibility analysis of source databases with available destination databases is supported. Destination databases can be selected by schema.

Manage a database profile

Application evaluation

The planning and evaluation feature is supported to migrate large-scale Oracle databases and applications. This feature can be used to analyze the associations among databases and applications and the compatibility between source and destination databases. The feature can be used to evaluate applications and databases, generate overall transformation solutions, and provide suggestions on the transformation sequence. The feature can also be used to analyze the compatibility of SQL statements in applications and provide corresponding transformation solutions.
